the hub of thewheel 7 is then supplied with i a flange 13-designed totake the pla'ce of the regular flange 9; The flange 13 is provided. withapertures lfadapted to receive; the bolts 10 for anchoring'the flange"to the hubof wheel 7 in the same manner as theflange 9- was formerlyanchored thereto. The flange 13 carries a bearing housing 15 inwhich isarranged an appropriate anti-friction bearing :16 preferably of the ballor roller type, or of any other appropriateandiwell known type. Tofacilitate assemblage, the outer portion of the shaft 11 is preferablyslightly reducediin diameter from the point indicated at 19 in Figure 2to the outer end of the "shaft.

Spaced inward from the point 19, shaft 11 is provided with an annularshoulder which may be produced many of'variou'slways, such as by thesecuring of a collar 1'7 or the for mation of an integral shoulder onthe shaft.

The s'houlder-thusformed is spaced from the point 19 along the shaft 11*a distance equal approximatelytothe width of the inner raceway ofbearing 16, and the diameter'of the shaft for this particular space ispreferably substantially equal to the diameter; of the bore of the innerraceway ofibearingr 16. V I Thus, incident to the reduced diameteroftherouter portion ofthe shaft (which reduction is'so slightas not to appearin thedrawing) the bearing 16n1'ayywhen the parts are being "assembled,be slipped readily onto the shaft 1-1" from the outer'end thereof untilit reaches 7 the point 19. Itinust thereupon be forced, further: ontothe shaft until it contacts with i the" shoulden formed by the collar orenlargement'17. 'Thus'the bearinghasa driven fit on the shaft and:itfi's also preferable to provide for asimilar driven fit ofthe outerraceway'of the bearinginthe bearing housing 15.
